 44 2020-04-15T02:19:34  <sipa> Apparently Satoshi also "buried" forks: https://github.com/bitcoin/bitcoin/commit/5cbf75324d1509a1262b65c5073314a4da3f6d77
 45 2020-04-15T02:20:55  <sipa> I wasn't aware before, but the 201 opcode limit, and the 20 keys in CHECKMULTISIG limit were initially only active for blocks >84000; in 0.3.13.5 it was changed to apply to every block
 46 2020-04-15T02:21:11  *** captjakk has joined #bitcoin-core-dev
 47 2020-04-15T02:27:50  <aj> block 84000 was a week away when the rule was added, and 10 days old when the rule was buried, give or take; neat
 48 2020-04-15T02:28:04  *** jb55 has joined #bitcoin-core-dev
 49 2020-04-15T02:29:19  <sipa> Yeah, best practices around timelines for these things *do* seem to have changed a bit since.
 50 2020-04-15T02:30:01  <sipa> Also, the commit message is great. "misc fixes"
 51 2020-04-15T02:31:44  <fanquake> I guess the covert change hiding commit messages have improved since then too
 52 2020-04-15T02:33:26  <sipa> i think satoshi wrote commit messages like we write release notes
 53 2020-04-15T02:33:47  <sipa> try to remember everything that changed since the last one, probably forget some parts
 54 2020-04-15T02:35:52  <midnight> satoshi hid all kinds of weird stuff that I wish he'd been more posthoc open about. :(

 58 2020-04-15T02:40:06  <sipa> midnight: i'm speculating of course, but i think he simply didn't really have an open-source minded process
 59 2020-04-15T02:40:46  <sipa> as in, i don't think he was trying to hide anything - i think he just didn't care enough to write good notes
 60 2020-04-15T02:41:45  <midnight> sipa: I felt the store-proxy-for-later-use-in-spite-of-what-the-user-wants was a bit anti-user.
 61 2020-04-15T02:42:33  <sipa> ?
 62 2020-04-15T02:42:57  <sipa> elaborate
 63 2020-04-15T02:43:52  <midnight> At one point I gave my bitcoind a proxy to connect through, which worked successfully. Later I wanted to stop using the proxy, but I hadn't correctly opened the network up on that machine. The proxy settings were stored in wallet.dat and (IIRC) the software tried to use it anyway when it couldn't connect normally. In my view this was super sneaky.
 64 2020-04-15T02:44:31  <sipa> heh, that sounds like a bug
 65 2020-04-15T02:44:33  <midnight> IMO based on his fairly mercenary attempt to force open incoming sockets for global connectivity it was a deliberate and not accidental design decision.
 66 2020-04-15T02:44:57  <sipa> at the time every setting was stored in wallet.dat
 67 2020-04-15T02:45:24  <midnight> I hope it was a bug, but..  he was pretty mercenary about incentives and user control. I hope it was buggy and not intended behaviour. :)
 68 2020-04-15T02:45:33  <sipa> of course - you may be right
 69 2020-04-15T02:45:52  <sipa> but also, don't ascribe to malice that which is adequately explained by incompetence
 70 2020-04-15T02:46:02  <midnight> He never answered my question about it. That was around the time people were bashing him a lot about code quality.
 71 2020-04-15T02:47:03  <midnight> I was trying to be polite but the avalanche of inexplicable "your code sucks" might have made me sound like them. Hope not. Maybe he just didn't get my emails. :)

 73 2020-04-15T02:49:22  <midnight> I don't think it was malice. Not quite how I'd describe it. More just.. taking user control out of the picture for the good of the early network.
 74 2020-04-15T02:50:09  <sipa> to an extent that is still the case - e.g. you can't request more than 8 outgoing connections
 75 2020-04-15T02:51:18  <midnight> Yeah I was okay with it. The source was available, and of course I could just manually edit wallet.dat to remove the proxy config.
 76 2020-04-15T02:51:38  <midnight> "You must be this tall to be able to control this feature.."
 77 2020-04-15T02:53:57  <midnight> Also possible: it was so long ago I am misremembering what actually happened and it was all just something I misconstrued. lol
 78 2020-04-15T02:59:04  <sipa> :)

302 2020-04-15T14:39:39  <theStack> i'm just running the fuzz test from #17860
303 2020-04-15T14:39:41  <gribble> https://github.com/bitcoin/bitcoin/issues/17860 | fuzz: BIP 42, BIP 30, CVE-2018-17144 by MarcoFalke · Pull Request #17860 · bitcoin/bitcoin · GitHub
304 2020-04-15T14:40:02  <theStack> can anyone tell me how i know if the fuzz test found something significant? (as far as i remember the fuzz test never stops, i.e. only after receiving CTRL+C)
305 2020-04-15T14:42:57  <jonatack> theStack: you'll see a crash like https://github.com/bitcoin/bitcoin/pull/18521#issuecomment-610826738

314 2020-04-15T14:50:56  <theStack> jonatack: thanks, good to know. i thought it *really* runs indefinitely in all cases and e.g. writes out a file in case of crashes

316 2020-04-15T14:54:02  <theStack> what if the error we want to trigger is not a crash? If we take BIP 42, that doesn't result in a crash, but inflation
317 2020-04-15T14:54:15  <theStack> how would the fuzzer know the condition of an, i call it "significant event"?
318 2020-04-15T14:56:25  <jonatack> theStack: the fuzzer may have an option to do that... i don't see one like that in test/fuzz/test_runner.py, but you can set -loglevel)#

327 2020-04-15T15:02:16  <theStack> andrewtoth: ah, just by using assertions -- that makes sense

330 2020-04-15T15:04:18  <jonatack> theStack: calling directly like you're doing is more useful for testing PRs with new harnesses

336 2020-04-15T15:13:02  <jonatack> theStack: makes sense, i seem to recall MarcoFalke saying the runner script was really for the ci, after instagibbs and i were trying to run it unsuccessfully a couple months ago
337 2020-04-15T15:13:47  <jonatack> i was just peeking inside to see the config options
338 2020-04-15T15:14:54  <MarcoFalke> test_runner is for running over all inputs, which is useful for running against every commit
339 2020-04-15T15:15:07  <MarcoFalke> So mostly ci, not for extending fuzz coverage
340 2020-04-15T15:22:36  <theStack> jonatack: MarcoFalke: ok, so i will ignore that script for now

489 2020-04-15T21:19:03  <BlueMatt> elichai2: yea, oss-fuzz has some rather-strict rules about how they will disclose issues publicly after N days of reporting them.

491 2020-04-15T21:20:08  *** captjakk has joined #bitcoin-core-dev
492 2020-04-15T21:20:11  <BlueMatt> elichai2: at the time, and imo quite reasonably, we decided that was completely unacceptable for a p2p consensus system which may, depending on the type of failure, require network-wide update for something to be safe, and some rapid disclosure policy is not compatible with that
493 2020-04-15T21:20:52  <BlueMatt> elichai2: also note that oss-fuzz primarily just provides cpu hours, it doesn't do any actual implementation work for you, and getting access to a few hundred cores for bitcoin core fuzzing is rather easy :p
494 2020-04-15T21:21:12  <sipa> BlueMatt: on the other hand, we currently have fuzzers for the codebase (yay), and we can't prevent anyone from running them secretly on a massive cluster
495 2020-04-15T21:21:13  <BlueMatt> (as a reminder: lots of cpu cores are available in a few locations for those doing bitcoin open source work)
496 2020-04-15T21:21:39  <BlueMatt> sipa: sadly they're mostly all kinda boring targets :(
497 2020-04-15T21:21:55  <BlueMatt> but we *have* a few rather reasonably-sized clusters in various places...
498 2020-04-15T21:22:01  <sipa> BlueMatt: have you paid attention to the more recently added ones?
499 2020-04-15T21:22:04  <BlueMatt> dont think any are currently fuzzing core, but...
500 2020-04-15T21:22:05  *** Frost1 has joined #bitcoin-core-dev
501 2020-04-15T21:22:50  <BlueMatt> ah, marco's fuzz stuff got merged! I missed that.
502 2020-04-15T21:23:52  <sipa> so perhaps... either we keep the more delicate ones private (how?), or we're ok with having the ones we have publicly participate in oss-fuzz?
503 2020-04-15T21:23:56  <BlueMatt> well, someone should give them more cpu hours. afair marco had previously done stuff, but...
504 2020-04-15T21:24:09  <sipa> of course - we can also just increase how much cpu we spend ourselves
505 2020-04-15T21:24:13  <BlueMatt> or we could, you know, use the cluster(s) we have to get fuzz hours :)
506 2020-04-15T21:24:31  <sipa> well, or both
507 2020-04-15T21:24:37  <BlueMatt> there's probably at least 120 cpu cores lying around for such usage, just need someone to step up and write scripts
508 2020-04-15T21:24:37  *** captjakk has quit IRC
509 2020-04-15T21:26:29  <BlueMatt> i mean how many cpu hours does oss-fuzz provide? I cant imagine it is anything significantly more than the 100 cores/project full-time that we already have?
510 2020-04-15T21:26:37  <BlueMatt> and the tradeoffs for using it...kinda suck
511 2020-04-15T21:28:39  <sipa> that's a great question
512 2020-04-15T21:29:07  <BlueMatt> we could also ask osuosl if heir CI cluster has free cores: https://osuosl.org/services/hosting/details/
513 2020-04-15T21:29:09  <sipa> if it's indeed not (significantly more than) 100 cores, there isn't much to be gained from using it
514 2020-04-15T21:29:23  <BlueMatt> a few bitcoin groups gave them some funds afaiu
515 2020-04-15T21:29:41  <BlueMatt> but, you know, we should probably use our own cpus first.

518 2020-04-15T21:30:33  <BlueMatt> anyway, really just need someone to step up and manage VMs that run fuzzing. I can help a bit, I have it all set up for rust-lightning and regularly pull ~100 cores for that, but I dont really have the bandwidth to manage that all the time, let alone also for core.

521 2020-04-15T21:31:48  <BlueMatt> someone just let me or dongcarl know and we can get you set up with a few VMs with a bunch of cores, I presume there's soeone at blockstream who can do the same
522 2020-04-15T21:33:24  <elichai2> BlueMatt: are these bare metal? because running something like this to detect improvements/regressions can be very helpful: https://perf.rust-lang.org/
523 2020-04-15T21:34:16  <BlueMatt> kvm, but there are separate bare-metal servers intended for benchmarking cc jamesob
524 2020-04-15T21:34:31  <BlueMatt> (which are slower, but bare-metal and more 'average-grade' hardware)
525 2020-04-15T21:34:58  <elichai2> yeah but sadly you need bare metal for profiling, VMs are too dynamic for that AFAIK
526 2020-04-15T21:35:10  <BlueMatt> right, kvm just for non-benchmark things
527 2020-04-15T21:35:28  <BlueMatt> we have ~9 servers which are provisioned bare-metal for benchmarking
528 2020-04-15T21:35:42  <BlueMatt> 9 being 8-outbound-1-target for ibd benchmarking :)
529 2020-04-15T21:35:51  <BlueMatt> though you'd have to ask james as to the status of those
530 2020-04-15T21:36:09  <elichai2> I have my own PC dedicated for profiling benchmarking, trying different system wide changes to Bitcoin Core
531 2020-04-15T21:36:33  <BlueMatt> anyway, hardware/cpu resources isnt the issue, just gotta have someone write bash scripts :)
532 2020-04-15T21:36:40  <BlueMatt> well, and babysit to watch for errors
533 2020-04-15T21:38:44  <elichai2> BlueMatt: from what I looked in oss-fuzz it looks really simple, You write a simple dockerfile to compile and run and that's about it https://github.com/google/oss-fuzz/blob/master/projects/libsodium/Dockerfile
534 2020-04-15T21:39:24  <BlueMatt> well by the time you've done that much work you might as well run it on our own hardware (without the aggressive public-disclosure timelines that may put bitcoin users at risk...)
535 2020-04-15T21:39:26  <elichai2> and if I understand correctly Google will actually pay you if you integrate into oss-fuzz https://github.com/bitcoin-core/secp256k1/issues/739 "We want to stress that anyone who meets the eligibility criteria and integrates a project with OSS-Fuzz is eligible for a reward."
536 2020-04-15T21:39:59  <elichai2> BlueMatt: right. the disclosure thing is a problem, I think they're saying either 90 days from finding or 30 days from fixing
537 2020-04-15T21:40:35  <BlueMatt> lol, thats kinda obnoxious that they're auto-opening issues on open source projects.
538 2020-04-15T21:40:39  <BlueMatt> isnt that against the github tos?
